AMD Radeon R300 Grenada is 380X, Fiji is 390X and Bermuda is 395x2

AMD Radeon R300 Grenada is 380X, Fiji is 390X and Bermuda is 395x2

Alright, it's time for some sugar and spice. New specs and codenames for AMDs upcoming Radeon 300 series have surfaced on the web. Initially you will see a Radeon R9 380X and R9 380 graphics released, these now fall under codename Grenanda.

 

Fiji and Bermuda (Radeon R9 390 & 390X & 395x2)

We start with Fiji, this will be an new GCN v1.3 based silicon, that GPU forms the basis of the high-end and enthusiast class products. Very little is know TBH. The latest gossip points towards 4,096 shader processors / GCN 1.3 architecture / 256 TMUs with 128 ROPs, and a 1024-bit wide HBM memory interface, offering 640 GB/s of memory bandwidth. We assume 4 GB will be defacto the the memory amount. Expect the R9 390, the R9 390X, and the 2x Fiji = Bermuda = R9 390X2 to be based on that GPU.

Grenada (Radeon R9 380 & 380X)

Grenada will be based on the good and relatively old 28nm fab process, the GPU will actually be refresh of Hawaii.  Here is the spicy bit as this is going to be rather disappointing for a lot of you guys, Grenada will have the same specs as Hawaii - 2,816 GCN stream processors, 176 TMUs, 64 ROPs, and a 512-bit wide GDDR5 memory interface and is tapping into 4 GB memory (fully usable we assume:). The GPU is different in the sense that it is going to have increased clock frequencies to beat the GTX 980 from Nvidia. We expect a similar TDP, yet better cooling we hope.


Hawaii GPU to be refreshed 

Tonga (Radeon R9 370 & 370X)

The second rumor is that Tonga (R9 285) which had a rather miserable launch will be re-used and form the basis of the Radeon R9 370 series. Tonga has  2,048 shader processors,  GCN 1.3 architecture, 128 TMUs, 32 ROPs, and a 384-bit wide GDDR5 memory interface. We expect these cards to have increased clocks and 3GB of graphics memory.

Trinidad (Radeon R7 360 & 360X)

Trinidad is the low-end segment, and will be the Radeon R7 360 & 360X. Very little is known however this will be a refresh based on Pitcairn.

Give me a Tonga based card on Steroids which beats standart 290 and with 4-6GB Ram with less then 200Watts and i go red with a DP1.2a Monitor.

Otherwise i go green with a G(ay)-Sync monitor and i always will go green until the Monitor DIE.

I really hate this GPU´s this days, why Intel cant make good GPUs, i m really sick of AMD and NVIDIA

IF we want to call cards like 370(x) rebrands, then nearly everything in history of x86 architecture has been rebranded.

Because while Tonga may have GPU compute/rendering part of Tahiti, it has only 256bit bus but has new display controller and TrueAudio, better tessellation. (this means architectural changes)
And if 370(x) is supposed to be Tonga based it would again have to have 256bit bus, but it apparently features 384bit bus.
(if anything, it is not rebrand, it is updated/upgraded Tahiti to GCN 1.3)

Anyway, this is like 5th rumor thread...

If the 380X will be as fast as the GTX 980 and cost like the gtx 970 or lower then gg nVidia :D

So if R380 is going to fight with GTX980, R390 should be really interesting card. interesting see what NV will come up with.
